Amazon Glacier

Материал готовится, пожалуйста, возвращайтесь позднее

Amazon Glacier is an extremely low-cost storage service that provides secure and durable storage for data archiving and backup. In order to keep costs low, Amazon Glacier is optimized for data that is infrequently accessed and for which retrieval times of several hours are suitable. With Amazon Glacier, customers can reliably store large or small amounts of data for as little as $0.01 per gigabyte per month, a significant savings compared to on-premises solutions.

Companies typically over-pay for data archiving. First, they're forced to make an expensive upfront payment for their archiving solution (which does not include the ongoing cost for operational expenses such as power, facilities, staffing, and maintenance). Second, since companies have to guess what their capacity requirements will be, they understandably over-provision to make sure they have enough capacity for data redundancy and unexpected growth. This set of circumstances results in under-utilized capacity and wasted money. With Amazon Glacier, you pay only for what you use. Amazon Glacier changes the game for data archiving and backup as you pay nothing upfront, pay a very low price for storage, and can scale your usage up or down as needed, while AWS handles all of the operational heavy lifting required to do data retention well. It only takes a few clicks in the AWS Management Console to set up Amazon Glacier and then you can upload any amount of data you choose.

Service Highlights

Low cost – Amazon Glacier is an extremely low-cost, pay-as-you-go storage service that can cost as little as $0.01 per gigabyte per month. With Amazon Glacier, there are no upfront capital commitments and all ongoing operational expenses are included in the price. You save money by paying only for what you use.

Secure – Amazon Glacier supports secure transfer of your data over Secure Sockets Layer (SSL) and automatically stores data encrypted at rest using Advanced Encryption Standard (AES) 256, a secure symmetric-key encryption standard using 256-bit encryption keys. You can also control access to your data using AWS Identity and Access Management (IAM). IAM enables organizations with multiple employees to create and manage multiple users under a single AWS account and to set resource-based access policies.

Durable – Amazon Glacier is designed to provide average annual durability of 99.999999999% for an archive. The service redundantly stores data in multiple facilities and on multiple devices within each facility. To increase durability, Amazon Glacier synchronously stores your data across multiple facilities before returning SUCCESS on uploading archives. Unlike traditional systems which can require laborious data verification and manual repair, Glacier performs regular, systematic data integrity checks and is built to be automatically self-healing.

Flexible – Amazon Glacier scales to meet your growing and often unpredictable storage requirements. There is no limit to the amount of data you can store in the service. Whether you’re storing petabytes or gigabytes, Glacier automatically scales your storage up or down as needed. In addition, you can choose to store your data in the Amazon Glacier Region that meets your regulatory, throughput, and geographic redundancy criteria.

Simple – Amazon Glacier allows you to offload the administrative burdens of operating and scaling archival storage to AWS, and makes retaining data for long periods, whether measured in years or decades, especially simple.
